IMPROVEMENT IN LAMP-WICKADJUSTERS.

Specication forming part of Letters Patent No. 211,160, dated January 7, 1879 application tiled May 27, 1878.

. evenly above the top of the tube, and thus insure an even well-shaped flame, it being well known that with an ordinary adjusting device it is necessary to trim the wick in case it burns unevenly, whereas with my invention either edge of the wick may be raised orlowered sufficiently to make it even with the other edge.

Said invention consists in combining with a tube of a keroseneburner two wick-adjusting spur-wheels, each wheel operating on the different edges of the wick, and each wheel being operated ,by an independent fingerwheel.

Figure 1 is a side elevation, showing my invention. (The parts of the burner which are not essential to a proper understanding of my invention are omitted.) Fig. 2 is an enlarged sectional view of the spur-wheels and their adjnncts.

Let O represent the wick-tube; D, a part of the body ofthe burner, and E the wick. These parts, as well as the parts which complete the burner, with the exception of the wiek-raising device, may be made in any desired style.

The spur-wheel A2, which operates on the wick E, is connected lbya shaft, A', to the iinger-wheel A, while the spur-wheel B2 is connected by means of a hollow shaft, B1, to the finger-wheel B, the shaft A1 passing through the hollow shaft B1, so that either one of the spur-wheels A2 B2 may be moved independently of each other, and thus either edge of the wick may be moved up or down sufficiently to even the burning part of the wick. To move the wick up an d down bodily both wheels must be moved; but to move one edge for the purpose of adjustment, one Wheel must be held while the other is being turned. If desirable, one of the linger-wheels can be at one side of the lamp, while the other can be placed at the opposite side.

From the above it may be seen that my device differs from the ordinary one, inasmuch as that, although other adjusters have the two spur-wheels to act one upon each edge of the wick, bot-h of these wheels are rigidly affixed to a common axis, so that they must both act together and neither can be moved independently of the other. Thus, if they move at all, both edges of the wick are raised alike, while in my device the two spur-wheels act independently of each other, and thus either edge of the wick may be raised or lowered, as may be required for the perfect adjustment of the burning end of the wick, to insure an even ame.

Having now described the construction and operation of my invention, what I claim, and desire to secure by Letters Patent, is as follows:

l. In a lamp-burner, the combination of the tube O, the two indejiiendently-moving wickadjusting wheels A2 B2, and a suitable operating mechanism, whereby the burning end of the wick may be adjusted evenly, substantially as described, and for the purpose set forth.

2. In a lamp-burner, the combination of the wick-tube O and the edge adjusting spurwheels A2 B2 with the quill and ringer-wheel B1 B andthe shaft and finger-wheel A1 A, substantially as described, and for the purpose set forth.
